Clinical assessment of nifedipine-induced gingival overgrowth in a group of brazilian patients.

Although it has been established that nifedipine is associated with gingival overgrowth (GO), there is little information on the prevalence and severity of this condition in the Brazilian population. The aim of this study was to assess the occurrence of nifedipine-induced GO in Brazilian patients and the risk factors associated using a Clinical Index for Drug Induced Gingival Overgrowth (Clinical Index DIGO). The study was carried out on 35 patients under treatment with nifedipine (test group) and 35 patients without treatment (control group).

Transformation of proliferative verrucous leukoplakia to oral carcinoma: a ten years follow-up.

Cyclosporin A-induced gingival overgrowth in renal transplant patients.

Background: The incidence of gingival overgrowth (GO) associated with the use of cyclosporin A (CsA) is controversial. In the present study, we determined the incidence of GO in Brazilian renal transplant patients treated with CsA and the possible associations between periodontal and pharmacological variables.

Methods: The test group consisted of 20 renal transplant patients, and the control group included 20 non-transplant patients.
